Optimización de la productividad mediante la aplicación de herramientas Lean Manufacturing en la empresa SIEXPAL S.A.

Abstract

The objective was to optimize productivity through the application of Lean Manufacturing tools in the company SIEXPAL S.A., in the city of Santo Domingo de los Tsáchilas, reducing production time by eliminating and improving processes and evaluating the feasibility of the proposed solution. The development of the work began with the identification of the current situation of production of palm kernel oil through the measurement of times, process diagrams, survey of the main indicators of the system, process analysis diagram, initial VSM and cost analysis. An initial productivity of 1.59 ton/hour, takt time of 17.2 min/ton, level of compliance with the 5'S pillars of 40%, 2 inoperative machines were found. Subsequently, a proposal was designed allowing the optimization of processes in the company by means of the implementation of a manual of processes and procedures and the implementation of red and yellow cards to apply the 5'S methodology. This standardization of activities resulted in an increase in compliance with the 5'S pillars to 78.67%, an increase in production 1.65 ton / hours and a decrease in takt time to 16.48 min / ton, through a socialization to the administrative and plant personnel of Siexpal S.A., Finally, the feasibility of the proposal generated was evaluated, obtaining as a result a period of 8.44 and 5.63 months of recovery of the investment for the change of the disabled machinery, being a viable alternative to increase the production capacity. By means of the paired statistical t-test the optimization of the system was verified applying the lean tolos and accepting the alternative hypothesis. It is recommended permanent trainings to the personnel to generate in this way a culture of continuous improvement of the performed activities.
